Definitions

  • the present invention relates to a solenoid valve device.
  • the invention relates to a solenoid valve device of the type comprising:
  • This solenoid valve comprises a single movable core, which, in the energized state of the associated solenoid, opens a passage provided in the main plug, thus putting the control chamber into communication with the outlet.
  • the solenoid In order to move this movable core, the solenoid must be energized by a rather high power (voltage).
  • One object of the present invention is to provide a solenoid valve device of the aforesaid type, made in such a way as to require a considerably lower electrical power for energizing the associated solenoid.
  • a solenoid valve of the type defined above characterized in that the aforesaid movable unit comprises an additional or second ferromagnetic core, mounted in said solenoid adjacent to one end of the aforesaid first core, and in that positioning means are provided for keeping the second movable core fixed to the main plug and, when the solenoid is inactive, for keeping the first core in the closed position of said second passage and the second core in a predetermined position with respect to the solenoid and to the first core, said cores being separated by a gap;
  • the arrangement being such that the energizing of the solenoid causes the attraction of the first core towards the second core and the opening of this passage.
  • the opening of the aforesaid second passage then allows the main plug to move away from the associated valve seat, and allows the direct passage of fluid from the inlet to the outlet through said valve seat.
  • a solenoid valve device in a solenoid valve device according to the present invention the second movable core is translated together with, and over the same distance as, the main plug, but the energizing of the solenoid only has to be sufficient to allow the first movable core to be attracted by the second movable core and to move over the small distance corresponding to the distance between said cores.
  • the solenoid regardless of the specified travel of the main plug, the solenoid only has to make the first movable core cover the small distance corresponding to the size of the aforesaid gap.
  • FIG. 1 is a partial view, in axial section, of a solenoid valve device according to the present invention
  • FIG. 2 is a similar view which shows a variant embodiment
  • FIG. 3 is a partial view, in axial section, of another solenoid valve device according to the present invention.
  • FIG. 4 is a partial view of a section taken essentially along the line IV-IV of FIG. 3 ;
  • FIG. 5 is a sectional view of another variant embodiment
  • FIGS. 6 and 7 are sectional views of further variant embodiments.
  • the number 1 indicates the whole of a solenoid valve according to the invention, which can be used for example to control the supply of water from the water mains to a machine for washing such as a washing machine or a dishwasher.
  • the solenoid valve 1 comprises a body 2 , made from moulded plastic material for example, in which an inlet passage 3 for a fluid (typically a hydraulic fluid) and an outlet passage 4 for this fluid are formed.
  • a fluid typically a hydraulic fluid
  • these passages 3 and 4 are coaxial, but this relative arrangement is not essential.
  • the outlet passage 4 is made in a tubular formation 5 of the body 2 , the upper part of this formation defining a main valve seat 6 . A flow of fluid can pass through this valve seat 6 from the inlet 3 to the outlet 4 .
  • a second body 7 also made of plastic material for example, is coupled to the top of the body 2 in a fluid-tight way.
  • a peripheral portion 8 a of an annular diaphragm indicated as a whole by 8 is clamped between the bodies 2 and 7 .
  • This membrane 8 comprises a flexible intermediate portion 8 b , which connects the peripheral portion 8 a to a thickened central annular portion 8 c intended to act as the main plug interacting with the valve seat 6 .
  • the portion 8 c is mounted around a shank 9 a of an essentially cup-shaped guide element 9 , and is secured on this shank by means of an annular element 10 .
  • the shaped body 7 has an upper tubular formation 7 a, closed at its upper end.
  • a control chamber is formed between the body 7 and the assembly formed by the diaphragm 8 and the associated guide element 9 .
  • the control chamber 11 is in permanent fluid communication with the inlet 3 , through at least one passage which, in the illustrated exemplary embodiment, is formed in the unit comprising the diaphragm 8 and the associated guide element 9 .
  • a plurality of through holes 8 d are formed in the portion 8 c of the membrane 8 , outside the valve seat 6 . These holes communicate with an annular compartment 9 b formed in the diaphragm guide element 9 , this compartment communicating in turn with corresponding outer grooves 9 c which are also formed in the diaphragm guide 9 .
  • communication between the inlet 3 and the chamber 11 can be established by means of passages provided in the diaphragm 8 and in the associated diaphragm guide 9 , or provided in the body of the solenoid valve device.
  • the number 12 indicates a passage formed in the diaphragm guide 9 , which can put the control chamber 11 into communication with the outlet passage 4 .
  • a tube 13 made of steel for example, is fitted in the upper portion of the passage 12 , this tube having a projecting upper rim 13 a which can act as a valve seat, as explained more fully below.
  • the solenoid valve device additionally comprises a control solenoid valve indicated as a whole by 14 .
  • This control solenoid valve comprises an operating solenoid 15 which is associated, in a known way, with a magnetic circuit comprising two tubular elements, namely an upper element 16 a and a lower element 16 b, which extend axially from opposite ends into this solenoid.
  • the corresponding ends of the elements 16 a and 16 b face each other at a predetermined distance, in an axially intermediate part of the solenoid 15 .
  • the assembly formed by the solenoid 15 and the associated magnetic elements 16 a and 16 b is mounted around the tubular portion 7 a of the body 7 .
  • the control solenoid valve 14 also comprises a unit indicated as a whole by 17 , which is mounted movably in the solenoid 15 , and, in particular, is mounted movably with a radial clearance within the tubular portion 7 a of the body 7 .
  • This unit 17 comprises a movable core 18 of ferromagnetic material, which bears on the valve seat 13 a in the rest state (when the solenoid valve device 1 is closed).
  • the movable ferromagnetic core 18 is mounted inside a spacer element 19 made from non-magnetic material.
  • the spacer element is tubular (although it could be made in other shapes) and extends with a radial clearance inside the tubular portion 7 a of the body 7 .
  • the lower end of the element 19 has a larger diameter, and bears on the diaphragm guide 9 around the valve seat 13 a.
  • the movable core 18 has a radial shoulder 18 a, and a coil spring 20 is positioned between this shoulder and a facing inner shoulder 19 a of the aforesaid tubular element 19 .
  • the spring 20 tends to push the movable core 18 against the seat 13 a so that the core acts as a plug.
  • a second ferromagnetic core, indicated by 21 is positioned above the tubular element 19 , in the portion 7 a of the body 7 .
  • a coil spring 22 is positioned between the upper end of the second core 21 and the upper end wall of the portion 7 a of the body 7 . This spring 22 tends to push the core 21 and the tubular element 19 downwards, particularly in such a way that the lower end of the tubular element 19 is kept in contact with the diaphragm guide 9 .
  • a spring 20 can be positioned in the gap 24 between the cores 18 and 21 in place of the spring 22 described above, in which case the element 19 and the core 18 do not have to be provided with the corresponding shoulders (as is seen in the variant shown in FIG. 2 ).
  • the tubular element 19 In the upper part of the tubular element 19 , adjacent to the core 21 , there is formed at least one aperture, indicated by 23 in FIG. 1 , through which the gap formed between the portion 7 a of the body 7 and the element 19 communicates with the gap formed between this element 19 and the lateral wall of the core 18 .
  • the spacer element 19 can be separate and distinct from the core 21 and from the diaphragm guide 9 , or can be integral with (or otherwise permanently fixed to) one and/or the other of the latter members ( FIG. 2 shows an embodiment which is similar to that of FIG. 1 , but which differs from it essentially in that the element 19 is made in one piece with the diaphragm guide 9 ).
  • the solenoid 15 when the solenoid 15 is inactive, the fluid supplied to the inlet 3 enters the control chamber 11 through the passage or passages 8 d, 9 b and 9 c.
  • the movable core and plug 18 closes the valve seat 13 a, and the control chamber 11 is brought to the same fluid pressure as the inlet passage 3 .
  • the portion 8 c of the diaphragm 8 which acts as the main plug, bears on the valve seat 6 , because the surface area of this diaphragm and of the associated diaphragm guide 9 exposed to the pressure in the chamber 11 is greater than the surface area of the membrane 8 which is exposed to the pressure in the passage 3 .
  • the main valve 8 c - 6 is therefore closed.
  • the fluid pressure in the control chamber 11 can then be discharged towards the outlet passage 4 , through the tube 13 and the passage 12 of the diaphragm guide 9 .
  • the fluid supplied to the inlet passage 3 of the solenoid valve 1 can then reach the outlet passage through the valve seat 6 .
  • the raising of the plug 8 , 9 causes the core 21 to be raised by a corresponding amount and to draw with it the core 18 which is magnetically attracted to it; the seat 13 a therefore continues to remain open.
  • the electrical power required to energize the solenoid 15 so as to create and maintain the attraction of the core 18 towards the core 21 is extremely low, and in particular it is independent of the opening travel of the main plug 8 , 9 .
  • the distance (the height of the gap 24 ) between the cores 18 and 21 is preferably less than the distance between the magnetic elements 16 a and 16 b, and the distance between each of the cores 18 and 21 and the associated magnetic elements 16 a and 16 b is also preferably less than the distance between the magnetic elements 16 a and 16 b.
  • the gap 24 across which the cores 18 and 21 face each other, is located in an area which is located between the facing ends of the magnetic elements 16 a and 16 b with respect to the axis.
  • the elements 16 a and 16 b can be omitted if required, and in this case the second movable core 21 preferably extends upwards to a point in the proximity of the upper end of the solenoid 15 .
  • fluid 3 flows from the inlet, through the passages 8 d, 9 b and 9 c, into the control chamber 11 , and then flows towards the upper part of the inner region of the tubular portion 7 a of the body 7 , through the gap formed between this tubular portion 7 a and the tubular element 19 .
  • This fluid can then flow back downwards through the aperture 23 and the gap formed between the tubular element 19 and the core 18 , towards the passage 12 - 13 and the outlet passage 4 .
  • the flow of fluid established in this way in the solenoid 15 advantageously reduces the temperature of the solenoid.
  • the unit formed by the diaphragm 8 and the associated diaphragm guide 9 can then return to the closed position of the main valve seat 6 .
  • FIGS. 3 and 4 show another variant embodiment.
  • parts and elements identical or functionally equivalent to parts and elements described previously have been given the same alphanumeric references as those used before.
  • the upper end of the passage 12 forms a projecting edge 13 which can act as a valve seat, as explained more fully below.
  • the solenoid valve device 1 illustrated therein also comprises a control solenoid valve 14 , comprising an operating solenoid 15 associated with a magnetic circuit comprising an essentially C-shaped shell 16 ( FIG. 3 ).
  • the assembly formed by the solenoid 15 and the associated magnetic shell 16 is mounted around the tubular portion 7 a of the body 7 .
  • the control solenoid valve 14 also comprises a unit indicated as a whole by 17 , which is mounted movably in the solenoid 15 , and, in particular, is mounted movably with a radial clearance within the lower tubular portion 7 a of the body 7 .
  • This unit 17 comprises a movable core 18 of ferromagnetic material, carrying at its lower end a plug 118 a which bears on the valve seat 13 in the rest state (when the solenoid valve device 1 is closed).
  • the movable ferromagnetic core 18 has a longitudinal passage 18 b within which a spacer element 19 of non-magnetic material extends.
  • the spacer element is in the form of a rod (although it could be made in other shapes), and extends towards the top of the element 9 of the main plug 8 , with a radial clearance through (and beyond) the passage 18 b of the core 18 .
  • a second ferromagnetic core, indicated by 21 is positioned above the spacer element 19 , in the portion 7 a of the body 7 .
  • a coil spring 20 is positioned between the core 18 and a facing shoulder of the core 21 .
  • the spring 20 tends to push the movable core 18 and the associated plug 18 a against the seat 13 .
  • a coil spring 22 is positioned between the upper end of the second core 21 and the upper end wall of the portion 7 a of the body 7 . This spring 22 tends to push the core 21 downwards, particularly in such a way as to hold the latter against the upper end of the spacer element 19 .
  • the spacer element 19 can be integral with (or otherwise permanently connected to) the diaphragm guide 9 (as shown in FIGS. 3 and 4 ) and/or the second core 21 .
  • the length of the spacer element 19 is such that, in the rest state of the solenoid valve 1 , shown in the figures, the cores 18 and 21 are separated by a narrow gap indicated by 24 .
  • the solenoid 15 when the solenoid 15 is inactive, the fluid supplied to the inlet 3 enters the control chamber 11 through the passage or passages 8 d, 9 b and 9 c.
  • the movable core and plug 18 closes the valve seat 13 , and the control chamber 11 is brought to the same fluid pressure as the inlet passage 3 .
  • the portion 8 c of the diaphragm 8 which acts as the main plug, bears on the valve seat 6 , because the surface area of this diaphragm and of the associated diaphragm guide 9 exposed to the pressure in the chamber 11 is greater than the surface area of the membrane 8 which is exposed to the pressure in the passage 3 .
  • the main valve 8 c - 6 is therefore closed.
  • the fluid pressure in the control chamber 11 can then be discharged towards the outlet passage 4 , through the passage 12 of the diaphragm guide 9 .
  • the fluid supplied to the inlet passage 3 of the solenoid valve 1 can then reach the outlet passage through the valve seat 6 .
  • the raising of the plug 8 , 9 causes the core 21 to be raised by a corresponding amount and to pull with it the core 18 which is magnetically attracted to it; the seat 13 therefore continues to remain open.
  • the electrical power required to energize the solenoid 15 so as to create and maintain the attraction of the core 18 towards the core 21 is extremely low, and in particular it is independent of the opening travel of the main plug 8 , 9 .
